The infinite notebook that will never run out of pages!

I'm designing an infinite notebook where you attach your spine size with a piece of filament.Then you place normal copy paper inside that you fix in place with a rubber band.But once you went through all pages you can archive your mad scribbles into an even bigger book version.

But the best part is that it's so thin at the front that you can write really comfortable.And the pen goes inside of the cover.Yes, I also made a mini version and I believe that this is my best design so far.
